In a pot over medium heat, bring enough water to cover sago pearls to a boil. Add sago pearls, stir gently, and cook for about 10 minutes or until translucent. Remove from heat, rinse well, and drain.
In the pot, add boiled sago and enough cold water to cover. Cook over medium heat, stirring occasionally, and bring to a boil. When water has boiled for about 6 to 10 minutes, remove from heat, rinse well, and drain.
In the pot, add enough cold water to cover the sago, and again, bring to a boil.
Repeat the process until the pearls are tender but chewy and translucent with no white in the center.
Under cold, running water, rinse sago a few times to remove excess starch.
Keep in a bowl of cold water or in simple syrup until ready to use.
